The Yankees’ superstar first baseman has a regimented routine before and after each home game. When the Yankees have night games in The Bronx, Teixeira leaves his house at the same time, splits up his car radio routine a certain way, is in the hot tub at the same time and wolfs down at least one peanut butter-and-jelly sandwich at the stadium.

Regimented? Teixeira is as strict with his routine as a rooster in the morning. He said his pregame habits have prompted Derek Jeter to dub him “The Robot.”

“I think it’s important to have a routine because when you do something 162 days a year, you want to make sure that you’re in the same place every day,” Teixeira said. “It allows you to get into a comfort zone.”

I figure out a routine every team I’m on. Every team I’m on, there’s a little nook of the clubhouse that you like to hang out or maybe there’s a place you like to watch TV before the game or whatever it is. But I just find that that puts me in the right place that I know where I’m supposed to be all throughout the day.”

Let’s go through Teixeira’s day for a normal 7 p.m. home game:

He typically wakes up by 10 a.m., then spends time with his kids before leaving his Greenwich home for the stadium at 2 p.m. On his drive — nobody else is in the car — Teixeira spends the first half of his commute listening to music (“everything from country to 70s to today.”) No talk radio — “It puts me to sleep,” he says.

As Teixeira nears New York City, he doesn’t get good reception on his stations, so he listens to a CD, and usually arrives at Yankee Stadium between 2:30 and 3 p.m.

“And then I’ll work out, whether it’s just kind of light stretching to get loose for batting practice or cardio — running, riding a bike. Or lifting weights,” he says, adding that his weightlifting involves alternating between two different workouts.

Teixeira grabs something to eat after his workout — and yes, that could be a peanut butter-and-jelly sandwich, because he eats more of them than your average kindergarten student. Next, Teixeira does batting cage work for 15-20 minutes — getting his hands loose, making sure his swing is OK, and working with hitting coach Kevin Long — before heading to batting practice. The Yankees usually hit from 4:40 to 5:40 p.m.

After that, Teixeira changes into shorts and a T-shirt and relaxes — “read the paper, have a cup of coffee, have my pregame meal.”

Teixeira said he doesn’t eat much and nothing too heavy — no pastas, but rather he eats a chicken breast with rice and beans. At 6:30, Teixeira hits the hot tub, then throws on his uniform and plays — and often collects a homer and a couple of RBIs.

After the game, Teixeira also follows a strict routine. He eats a bigger meal than in pregame, pounds his two waters, takes a shower, talks to the media and drives home (drinking his third bottle of water).

“I love to stay hydrated,” he says. “I learned that in Texas.”

Teixeira says this adherence to a regimented schedule began in high school when he had to balance classwork with sports.
